HAI part numbers

[dementeddigital]

Is there a Rosetta Stone somewhere that lists the HAI part numbers and their differences?
 
I have a 20A01-31, and I can't tell if it's an OnQ variant or if it's a true Omni Pro II (or something else entirely!)
 
Can someone please orient me?
 
Thanks!

I believe you have an Omni IIe board.....
